PAL-18

High-end in different sizes

For superior low frequency vibration isolation: PAL high-quality air springs are designed for conditions in which the user wants to ensure that equipment is constantly level and isolated from vibrations at the same time.

The PAL system is an air spring system with level control that reacts quickly to loads and centre-of-gravity changes and adjusts deviations from the pre-set position automatically. The system is available in three different sizes for loads from 36 kg to 42,000 kg per air spring with a natural frequency up to 1.7 Hz. Customised isolators with a natural frequency of up to 0.5 Hz can be manufactured upon request.

The springs ensure perfect results in sensitive areas such as on measuring equipment, aircraft or automotive test stations, as well as in other areas, such as foundation mountings.Learn More ...

Application Examples

PAL - Glass measuring table, ambient vibrations

Measurements made on a glass measuring table led to unusable results because the isolator used was unable to cope with the lateral stiffness of the products used. Only low-frequency pneumatic isolators with automatic level control of the type PAL 21-6 ACE could provide a remedy. A special feature of these membrane pneumatic isolators lies in the level control valve, which has, by virtue of its ...

Application Areas

test and calibration appliances

aircraft and car testing stations

foundation mounting
